If you suspect your sheep might have pneumonia, watch out for symptoms such as lethargy, depression, loss of appetite (or the sheep being “off its feed”), and isolation from the rest of the flock. For recovery’s sake, place the sick sheep in a warm and dry environment. This will help it handle its symptoms better, as humid environments can exacerbate breathing problems and extreme temperatures can hinder recovery.

If you’re not sure how to deliver an injection, have your vet show you how to do it while they are on the farm assessing your sheep. If your animal has a fever, give it an acetaminophen, such as Tylenol. Ask your vet about the proper dosage. You can give these orally in your sheep’s food. If your sheep is not eating, your vet may give you a liquid or injectable form that can be forcibly administered.

In extreme cases, the sheep may stop eating altogether despite medications and need a feeding tube to be inserted in its stomach. Your vet will make this assessment. If your sheep is not drinking, make sure to give it electrolytes. If it has no interest in water, you can give an electrolyte mixture, purchasable at any feed store, through its mouth forcibly. It can be mixed into a syringe that can be squirted into the sheep’s mouth, or put in a bottle for lambs. [3] X Research source

These parasites are usually internal and require an injectable anthelmintic (antiparasitic) medication, such as Moxidectin or Ivermectin. The dosing is based on the weight of the animal and can range from 1 fluid ounce (30 mL) per 100 pounds (45 kg) or 1 millilitre (0. 034  fl oz) per 10 pounds (4. 5 kg).

Watch how your sheep interacts with the flock. If it is having trouble keeping up with and interacting with the rest of the flock, it may be coming down with an illness. You may notice it standing by itself, away from the flock.

If you have never used a rectal thermometer, consult your vet or a friend so that you do not cause any damage to the animal.

It’s normal for an animal to have quickened, labored breathing in hot weather, so make sure to take the setting and circumstances into account.

In its more developed stages, the sheep may have a frothy discharge coming from its mouth caused by difficulty breathing.

Make sure to keep the barn properly ventilated. Stagnant air can cause breathing problems.
